Ameren Illinois Company (AILLO): fair value, margin of safety and Wheel Score
Utilities · Regulated Electric · United States · High Growth
Is AILLO undervalued?
Ameren Illinois Company (AILLO) closed at 65.25 on 16 Oct 2026. The GLS average fair value - the simple average of the 7 valuation models that produced a positive number - is 128.02, which puts the price 49% below it. 4 of the 7 models value the shares above the current price. A gap this wide is rare in our universe of ~7,400 US stocks and is exactly what the Value part of the Wheel Score rewards; it is also where the question "why is it this cheap?" matters most.
There is a wide gap between DCF (10.54) and Graham Growth (351.30). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files AILLO under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Quality and financial health
Ameren Illinois Company scores 6 of 9 on the Piotroski F-score: a middling result that passes the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. On durability AILLO scores 5.6/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are high - ROIC 18.5%, ROE 18.6%, ROA 7.1% - with debt at 0.00 times equity and negative free cash flow.
The dividend yield is high at 6.51% (payout ratio 20%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual. Revenue comes mainly from Electric 81%, Natural gas 19% (quarter Q2 FY2026).
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 18.5% |
|---|---|---|---|
| GLS Moat | 5.6 / 10 | ROE | 18.6% |
| Debt / equity | 0.00 | ROA | 7.1% |
| Free-cash-flow yield | -70.9% | Payout ratio | 20% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 39: No options
No options are listed on Ameren Illinois Company in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 39) and the stock is left out of every options screen; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 0k shares a day on a market cap of $1.7B, with a beta of 0.10 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 9 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 49% margin of safety | |
| Health | 13 / 20 | Piotroski 6/9 | |
